T/F Zoo li qhov pom spectrum , ib atomic emission spectrum yog a tsis tu ncua ntau yam xim . T / F Txhua lub ntsiab lus muaj qhov tshwj xeeb atomic emission spectrum . T/F Qhov tseeb tsuas yog qhov tseeb xim tshwm nyob rau hauv ib lub ntsiab atomic emission spectrum qhia tias tsuas yog qee qhov frequencies ntawm lub teeb tso tawm.
Ua kom pom qhov no, koj puas tuaj yeem pom lub wavelength ntawm lub tsheb nrawm?
Yog koj ntsia ze, koj puas pom lub wavelength ntawm ceev ceev - lub tsheb txav ? Koj ua tau tsis qhia txij li nws yuav nyuaj rau tsom mus rau kev vibrations ntawm lub tsheb . Siv de Broglie qhov sib npaug, λ = h/mv uas yuav muaj qhov loj dua wavelength , ib slow- tsiv proton lub a ceev - tsiv golf pob? Piav koj cov lus teb.
Ib yam li ntawd, yog vim li cas atoms emit ib tug meej kab spectrum ntawm tsuas yog ib co energies es tsis txhob ntawm ib tug tas mus li spectrum ntawm tag nrho cov energies? Muaj kev sib raug zoo ntawm cov qauv atomic ntawm ib qho atom thiab nws spectral yam ntxwv. Atoms ntawm tus kheej cov ntsiab lus tawm teeb ntawm nkaus xwb wavelengths, ua a kab spectrum es tus nruam spectrum ntawm tag nrho cov wavelengths uas ua los ntawm cov khoom kub.
Tsis tas li ntawd, qhov atomic emission spectrum quizlet yog dab tsi?
Atomic Emission Spectra . Cov kab tsis txuas ntxiv spectrum ntawm lub teeb tsim thaum muaj kev lom zem atoms rov qab mus rau lawv lub xeev hauv av thiab emit photons ntawm qee zaus. Atomic Kev nqus Spectrum . Cov spectrum ntawm tej yam absorbed wavelengths ntawm lub teeb sib xws rau ib atom lub spectrum ntawm tso tawm frequencies ntawm lub teeb.
Puas yog atomic orbitals muaj qhov loj me me?
atomic orbitals ( ua , ua tsis yog) muaj qhov loj me me . Txhua orbital tej zaum yuav muaj ntau tshaj (ob, plaub) electrons. pob s orbitals yog (spherically zoo li tus, dumbbell zoo li tus). ntau tshaj plaws (electrons, orbitals ) ntsig txog txhua theem ntawm lub zog tseem ceeb sib npaug 2n^2.

Puas yog cov plaub hau daj lossis cov plaub hau xim av muaj ntau dua?
Cov plaub hau xim av yog qhov tseem ceeb tshaj cov plaub hau daj. Cov me nyuam uas muaj ib tug xim av-haired allele thiab ib tug blonde-haired allele yuav nthuav cov plaub hau xim av thiab. Tsuas yog cov uas muaj ob lub ntsej muag plaub hau daj yuav muaj cov plaub hau daj
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Puas yog txhua yam muaj sia ua los ntawm ntau tshaj ib lub xov tooj?
Cov khoom muaj sia feem ntau yog tsim los ntawm ib lub cell thiab lawv hu ua unicellular organisms. Ntau yam muaj sia nyob yog tsim los ntawm ntau lub hlwb uas tsim cov nroj tsuag loj lossis tsiaj. Cov tsiaj muaj sia no hu ua multicellular organisms. Dej ua kom txog li ob feem peb ntawm qhov hnyav ntawm cov hlwb
Yuav ua li cas muaj ntau yam genotypes muaj peev xwm rau lub tsho tiv no Xim nyob rau hauv luav?
Plaub qhov sib txawv muaj nyob rau hauv cov xim luav (C) gene
Dab tsi yog qhov emission spectrum ntawm lub hnub?
Lub emission spectrum ntawm lub hnub. Lub hnub emits hluav taws xob hluav taws xob hluav taws xob hla ntau lub wavelengths. Qhov siab tshaj plaws nyob rau hauv lub hnub ci emission spectrum yog li ntawm 500 nm, nyob rau hauv lub xiav-ntsuab ib feem ntawm pom spectrum. Raws li lub teeb pom kev, Lub Hnub emits ultra violet hluav taws xob thiab hluav taws xob infrared
